Another attempt to use Emacs shell where CDPATH is colliding with
eshell. Directory Software/ is there, it even expands by using TAB to
add the slash / on the end of word Software. So if it expands it does
find the directory, but then collides something with CDPATH

Welcome to the Emacs shell

~/Programming $ cd Software/emacs/
